So, I googled you and found out more about your business. There is a tandem cycle club that comes to our area every year. We pass them on our way to church. Someone once asked if my husband and I would like to rent a tandem cycle. As far as I am concerned, it would be a big fat ticket to disaster. We get along by Not doing things in close proximity. Nose to back on a bicycle?.......No. We greatly admire those who do because it has to take coordination and cooperation of the highest order, or everyone ends up in a ditch or pasted to the front of a car. I look forward to reading the rest of your story.
